In your Model that uses the compound keys, simply put use SebWas\Laravel\Eloquent\CompoundKeys;. If another Model is referencing this through a HasManyThrough relationship, use the SebWas\Laravel\Eloquent\CompoundKeysRelationship trait with it.

There are a few limits to this, that can be solved by overriding the functions and re-implementing them properly.

• The static destroy can't be called
• The morphTo relationship won't work
• HasManyThrough's getHasCompareKey doesn't work
• Some other functions, especially on relations may be buggy
